4K7 resistor network, any TV techs remember seeing them in sets and if so which? I would imagine mid to late 70's use. Also would they be 1W or 3W

Thorn used these in their 9K & 9K6 series sets. I can't remember the particular values though.
Best regards

Hi Mike,
Now you mention it I seem to recall something similar on my Thorn 9905 chassis.

They've shown up in various sets over the years. The early type were actually individual resistors potted in clay. These are thick-film units and probably 70's/80's
8137 could be a date code...37 week of 1981
We used to use lots of these as termination resistors on parallel data links (like SCSI etc) in the late 70s.
From memory the individual resistor power rating was only 0.25W

Not necessarily 4k7, but arrays featured a lot with things like 7 segment displays, keeping PCBs neat, compact and quick to load.
Yes, 9 pins, one common and 8 resistors. Ideal pull-up resistors for 8-bit devices!
When all else fails, read the instructions
